This major sustainability-focused refurbishment will transform and extend the existing multi-tenanted Grade II listed building, creating over 20,000 sqm of open-plan workspace through sensitive engineering interventions. At ground level, 2,753 sqm of retail space will be added, incorporating three restaurants and various co-working facilities.
Major alterations include the recladding of two elevations and the reconfiguration of the ground floor reception areas. Elsewhere, existing office spaces will be refurbished to CAT A, two new floors will be added, and a new roof top plant area will be incorporated, whilst a double-mansard roof extension will provide an eighth floor, creating terrace spaces.
Our team is providing building services, structural engineering and environmental input for the scheme. Focusing on the retention of existing building elements and the re-use of materials, the design reduces embodied carbon whilst maximising future adaptability.
A philosophy of balancing maximum flexibility with embodied carbon was adopted throughout the design process, helping to ensure the longevity of the interventions. This included strengthening rather than replacing the existing structural columns, minimising the weight of the new façade and utilising a lightweight structural steel solution for the extension.
Our MEP design drives-down predicted operational carbon through the use of Low and Zero Carbon (LZC) technologies. By utilising heat pumps, energy-efficient lifts and LED lighting for the offices, emissions will be cut by half compared to pre-refurbishment levels. New floors include high-performance façades which will reduce heating and cooling loads, while Underfloor Air Distribution (UFAD) will be used throughout to help achieve a 35% CO2 reduction compared to construction standards.
